Don't confuse the guy. If he doesn't know how to use ping correctly I
don't think he's going to understand what you just said. The bottom line
is that you can't/don't ping URLs, you ping host records/DNS entries,
and IP addresses.

Is this incorrect?

Well, not exactly ping is a program that sends an ICMP message (echo
request) to a machine.  as with most (all?) tcp/ip networking programs
if the host given as an argument is not recognized as an ip address, a
call to a name resolution routines like gethostbyname() is made to map a
host name to an ip address.  

This is where DNS comes in.  a typical linux host configuration will
look in the file /etc/hosts an if not found will ask the dns server
defined in /etc/resolv.conf for the ipaddress of the hostname. It can
take a while for the name resolution to time out.  

> Try 'ping monolith' or 'ping http://monolith' and see what you get.
I've never seen an http address without a top level domain (i.e. .com,
.net, .org, etc.) so I'd be surprised if either of those worked.
> 

I agree, that pinging monolith will let you know if the name resolution
is working.

I would compare the /etc/hosts and /etc/resolv.conf files between the
working and not working machines.

That's because the path that leads to traceroute is not a part of a regular user's 
environment. You have to specifically call it. Use 'locate traceroute' to find out 
where it is.

Yes you are. You (not you specifically, but people in general) don't ping webpages, 
you ping DNS records.

Try 'ping monolith' or 'ping http://monolith' and see what you get. I've never seen an 
http address without a top level domain (i.e. .com, .net, .org, etc.) so I'd be 
surprised if either of those worked.

I can bring the man pages up on traceroute but it comes up with the error 
command not found.

As well I can ping web pages like google but I can't do it to our intranet. 
This web page is inside of our network.

This is what I am typing:

ping http://monolith/front_page/MFW_index/htm

Am I missing something here?

Try 'traceroute ' and see if some of the computers are having a 
hard time resolving the ip address. Sounds like a DNS issue.

Also, did you try using other browsers for the off chance it's something 
related to the browser?

I have 22 workstations that have all the same hardware and software.

Some machines are running great. They are pulling our intranet up quickly 
and then I have other machines that are taking forever to pull the page up. 
The page isn't flash based at all so I am thinking this is more of a 
networking issue. The NIC's ar running 100 full duplex.

Can someone point me in the right direction to see why these machines are 
having issues.

this is usually a driver option, but without knowing what driver your
using it is difficult to tell you what option to use.

a good resource for linux network drivers:

http://www.scyld.com/network

a good deal of drivers originate from that author, so chances are good
you may find the info you need there.

You should be able to do this using the software that came with the NIC

disk

Autonegotiation is not a reliable feature of neither hubs, switches or
NICs. Your best chance for success is to force both ends to the speed
and duplex mode you want.

Your switch will have a vendor (and model somtimes) dependent procedure
to do this. Under linux, use the mii-tool program to set/query the NIC's
parameters. Try man mii-tool for more information.

This depends on the kernel module which is used by the card.
Some of the modules take options from /etc/modules.conf but
you'll need to check the Ethernet-HOWTO [1] and the source
for the module you're using to be sure.

auto negotiation is unreliable at best.  i suggest going to donald beckers 
website, he wrote most of the network drivers in linux.  he has some 
configuration programs you can compile to set your card to force 100fd or 
whatever you want in the prom.

http://www.scyld.com/diag/

also, most of the time you can also set this via /etc/modules.conf, by 
passing some parameters to the module.  check out another becker webpage, 
there is loads of information there.

http://www.scyld.com/network/

hope this helps

If you have a 10/100 card, it should auto-negotiate with the switch/hub

It's supposed to, but sometimes autonegotiation doesn't always work
right. Those who use cisco know it only too well.

So I need to force the card to use full-duplex.

Isn't that handled automatically by the card?

Actually, I'm trying to find some information about this myself. I have
a server with a quad-port PCI ethernet card, made by Tulip. This is what
dmesg shows:

Linux Tulip driver version 0.9.15-pre2 (May 16, 2001)
tulip0:  EEPROM default media type Autosense.
tulip0:  Index #0 - Media MII (#11) described by a 21142 MII PHY (3) block.

eth4: Digital DS21143 Tulip rev 65 at 0xc480, 00:80:C8:B9:C0:55, IRQ 10.

I have connected eth4 to an HP4000M core switch at our provider, and
that switch port is set to 100MB, full-duplex. However, the message in
the /var/log/messages file of this server shows:

Jun 11 16:35:25 ETR1500 kernel: eth4: Setting half-duplex based on MII#1
link partner capability of 0081.

Is there any way I can force this eth4 port to full duplex? I tried to
look in the ifconfig man page, but I could not find any relevant option.

Sorry, my bad. I obviously missed the shift key. It's 3MBs. Still kind of 
slow, but I found the culprit in the incredibly slow speed of my server's 
drive.

No problem. I have wondered about things like that myself. Questions 
like how do I test the speed of a links so that I know is limit. What 
components exists in either computer or within the network that might 
also restrict data flow?

The whole area of networking is data flow. Like water running through a 
pipe. Some are bigger than others. Some have more valves in the way. Its 
an end to end path that needs to be taken into account.

3Mbps or 3MB/s? There's a big difference.

It looks like, in my case anyway, that the old UDMA33 drive in my server is 
the bottleneck. hdparm -t reports it as doing buffered reads at a little 
under 4 MB/s, which is about the speed I am getting, minus a bit for network 
overhead. I do intend to replace it, but I might just move the timescale up 
some now :) 

Thanks for the response. I didn't really know all that much about hdparm. 
I'm going to have to look into it a little more.

This is something that I have found confusing myself. If the card's speed
is 100 Mbit / sec. Don't I have to first translate that from bits to byte
and account for any overhead? If I did that then with a standard 8 bits /
1 byte then I take the 100 x 10^6 Bit / sec = 12,500,000 byte /sec. How
much is taken up with a standard Ethernet communication overhead (30%)? If
we assume an unreal world number of 0% then the above transmission speed 
is rather slow in comparison to the ideal. Yet we our HDs IDE/SCSI 
controller should typically be faster than 12.5MB/sec so where is the 
bottleneck? You might test each HD via hdparm and see what the average

Run a google search for Donald Becker's mii-diag utility.  It tells you
the state of the ethernet framer and even lets you tweak some settings.

Hey guys,

Got a network question for you.  I have a customer trying to find out
the speed of his network connection.  He is running an Intel
Extherexpress Pro.  Is there any way for him to determine its speed
under RedHat Linux 6.2.  I know with the Digital Tulip Cards that if you
run it with the De4x5 driver, it will throw up a message telling you
what speed, but the Intel driver does not do this.  Any information
would be great.

Thanks
